Forge app error “No mime type could be found for file favicon.ico”

Apps generated using JBoss Forge get this error showing up in the server log:

JSF1091: No mime type could be found for file favicon.ico.  To resolve this, add a mime-type mapping to the applications web.xml

This is described in this bug:

The quick fix is to add this to your web.xml:


JSF conditional text output

Use an EL expression in the rendered attribute, for example:

<h:outputText value="some conditional message" rendered="#{! empty someManagedBean.someProperty}" />

Setting the default/welcome page for a JSF app

Since <welcome-file-list> only works with physical files, you cannot use a *.jsf filename here since this resolves to a different physical file (like *.xhtml).

To define a welcome file, use one of the following approaches:

    • add an index.html file, and include a refresh meta tag in the head:

      <meta http-equiv="Refresh" content="0; URL=your_welcome_page.jsf">


  • add an index.jsp file, and redirect to your welcome page:

    <% response.sendRedirect("dropdowns.jsf"); %>

Initializing a JSF ManagedBean

Sometimes things really are easy – the fact that I Googled how to do this now seems pretty silly. The more I use JSF the more I like it 🙂

To initialize the state of the ManagedBean that a JSF page is using (like to preload data, or initialize other displayed values), just call the code from the bean’s constructor. Simple as that.

For example

public class ExampleController
    private String exampleProperty1;
    private String exampleProperty2;

    public ExampleController()
    //example init code here, e.g. to init property values
